Abstract (en)

[origin: FR2824561A1] Polymerization of chloroprene, or a mixture of chloroprene and up to 20 wt.% of a comonomer, in aqueous emulsion in the presence of radical initiators at 5-70 deg C is effected in the presence of a copolymerizable surfactant (I) selected from hydrocarbyl maleate or maleamate salts or their derivatives. Polymerization of chloroprene, or a mixture of chloroprene and up to 20 wt.% of a comonomer, in aqueous emulsion in the presence of radical initiators at 5-70 deg C is effected in the presence of a copolymerizable surfactant of formula (I): R<3>-Z-CO-C(R<1>)=C(R<2>)-COOM (I) R<3> = 10-20C aliphatic or aromatic hydrocarbyl; R<1>, R<2> = H or 1-3C alkyl; Z = O or NH; M = alkali metal or NH4. An Independent claim is also included for a chloroprene homopolymer latex produced as above in which the latex particles have surface carboxy groups in an amount of 3-30 meq/100 g.
